I have also read news on this site saying that all future 1 and 2 series models would use 4 cylinder engines at the largest. As in the M2 would also have some sort of I4 engine. This really isn't so surprising when you consider that journalists have already been test driving Mercedes's upcoming A45 AMG and CLA45 AMG which have turbo 2.0L I4 engines making 350 horsepower.
BMW could easily make that sort of number by starting with their N20, maybe boring it out a little, maybe upgrading to a twin turbo setup, and then just tuning it more aggressively.
